模型
通过主观意识借助实体或者虚拟表现，构成客观阐述形态结构的一种表达目的的物件（物件并不等于物体，不局限于实体与虚拟、不限于平面与立体）。模型≠商品。任何物件定义为商品之前的研发过程中形态均为模型，当定义型号、规格并匹配相应价格的时候，模型将会以商品形式呈现出来。从广义上讲：如果一件事物能随着另一件事物的改变而改变，那么此事物就是另一件事物的模型。模型的作用就是表达不同概念的性质，一个概念可以使很多模型发生不同程度的改变，但只要很少模型就能表达出一个概念的性质，所以一个概念可以通过参考不同的模型从而改变性质的表达形式。当模型与事物发生联系时会产生一个具有性质的框架，此性质决定模型怎样随事物变化

Passage2The way people work has changed. The increasing use of technology presents new and continual challenges to small and large businesses，employees and managers，teachers and students.Everyone，it seems，is being affected by the technological revolution. Store clerks，for example，now use increasingly complex computerized cash registers，while university professors must learn to adapt their teaching skills in order to lead distance learning course.In today's world，training and learning do not stop when we finish school；they must now continue throughout our working lives. The Hong Kong government conducted a survey on the employment concerns，and training needs of its workforce. For many managers and other professionals the biggest challenge，as well as change，in the workplace，was the increased use of computers and computerized machinery or equipment. The need for experienced employees who could use this kind of equipment rose drastically. Many of those in the workplace at this time experienced changes in job requirements and had to attend job-related training or re-training courses.The changing work environment is also affecting education and how we learn. In Finland, a report on strategies for education and training in the information age discussed the changing roles of both teacher and student. With the increased use of technology and the growth of distance learning, the teacher has become more of a tutor who guides a student, rather than a lecturer. In turn, the student has to take more responsibility for his or her learning in the absence of direct teacher contact. The report also stressed that high school and university students should learn computer skills in order to cope with the demands of the future workplace.The Finnish report also highlighted the need for teacher training, and re-training, and suggested that the salaries and job descriptions of teachers be reviewed because of future demands expected in their jobs. Previously university professors may have held lectures between the weekday hours of 9:00A.M. and 5:00 P.M. in large halls filled with students. Now, they may spend part of their day lecturing larger groups of students on campus, and then conduct afternoon or evening classes online, with students in five different countries.As technologies grow and develop, ongoing training will continue to be necessary. To be successful in the workplace, people will not stop learning when they leave school-lifelong learning will become a way of life.The survey conducted by the Hong Kong government showed that________.
